Terry Francona's two-run single off third baseman Terry Pendleton's glove in the 10th inning yesterday in St. Louis gave the Montreal Expos a 6-5 victory over the Cardinals and Joaquin Andujar.

Francona's hit kept Andujar (19-7) from becoming the major leagues' first 20-game winner.

The victory went to reliever Gary Lucas (4-2). Jeff Reardon got his 31st save.

St. Louis remained in a tie for first place in the National League East with the New York Mets, who lost, 5-0, to the Pittsburgh Pirates. The Expos pulled within four games of first place in the division.

"You guys keep writing about that it's a two-team race with New York and St. Louis, and I can see that because they've been tied and so forth," Francona said. "But we have always thought of it as a three-team race all along. We just need to keep playing good ball."

Tim Raines led off the 10th inning with a double and Vance Law walked on four pitches. After Andre Dawson grounded out, advancing the runners, Ken Dayley relieved and walked Hubie Brooks intentionally. Francona followed with his hit.

After giving up a bases-loaded walk to Pendleton, Reardon got the last two outs in the Cardinals' 10th. He struck out Andy Van Slyke for the final out.

"We did exactly what we wanted to do: take two in St. Louis," Expos Manager Buck Rodgers said. "We lost the first one and then had to go against (John) Tudor and Andujar and that's tough. It's fun to be in the pennant race the last six weeks of the season."
